Question 1: The distance from the sun to the planet remains constant as this motion happens.
Question 2: The greater the distance, the slower the orbital velocity.
The factor that remains constant as the line between a planet and the sun sweeps out two equal areas at different places in its orbit is:
- The planet's speed as it sweeps out the areas.
As for the relationship observed by Kepler between a planet's orbital velocity and its distance from the sun, it is:
- The greater the distance, the slower the orbital velocity.
To answer these questions, let's break down the information and use Kepler's laws of planetary motion.
Kepler's second law states that a line connecting a planet to the sun sweeps out equal areas in equal time intervals. This means that even though the planet's speed may change as it moves along its orbit, the rate at which it sweeps out areas remains constant.
So, the factor that remains constant as the planet moves along its orbit while sweeping out equal areas is the planet's speed.
Now, let's move on to the second question. Kepler observed a relationship between a planet's orbital velocity and its distance from the sun.
According to Kepler's third law, the square of a planet's orbital period (the time it takes to complete one orbit) is proportional to the cube of its average distance from the sun. This means that as the distance between a planet and the sun increases, the planet's orbital velocity decreases.
Therefore, the correct relationship Kepler observed between a planet's orbital velocity and its distance from the sun is: The greater the distance, the slower the orbital velocity.
To summarize:
1. The factor that remains constant as the planet moves along its orbit while sweeping out equal areas is the planet's speed.
2. Kepler observed that the greater the distance between a planet and the sun, the slower the orbital velocity.
